8. Pet emergency
This excuse will work wonders with some professors – so use it only on those who love animals. Those who don’t may not be as tolerant as you would expect. What kind of pet emergency? Taking your dog to the vet because he was sick is simple and good enough. Always remember the simplest is the best. The more you talk the more it would seem like a lie, and your need to justify yourself will become obvious. Just think about it, if you really had to take your dog to the vet you wouldn’t talk more than that, right?
